nniT-En STATES WILLIAM F. SEIIJEL, OF ELKHART, INDIANA VALVE CONSTRUCTION FOR MUSICAL HORNS.

Application filed October 31, 1914. Serial No. 869,557.

To all whom it may concern:

Be it known that I, \VILLIAM F. SEIDEL, a citizen of the United States of America, residing at Elkhart, in the county of Elkhart and State of Indiana, have invented certain new and useful Improvements in Valve Construction for Musical Horns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to musical horns, such for instance as cornets and other similar instruments, and it is the object of the invention to simplify the construction of valve mechanism. In the present state of the art instruments of this character are provided with key-operated valves, which when adjusted alter the length of the tubular passage to change the pitch. In one type of valve pistons are employed which are longitudinally reciproca'ted, and a plurality of cross-ports in the piston are provided for connection between the different tubes. Usually each piston is provided with three cross-ports, one of said ports being in normal registration to provide the open passage through the horn and the other two ports being used for cutting in the crookwhich alters the pitch. Difliculty has been'experi'enced in forming such a construction so as to prevent interference between the several ports and at the same time to limit the length of stroke. With my improvement I have simplified the construction by dispensing with one of the ports,

thereby increasing the amount of clearance space as well as decreasing the length of the stroke. I have also modified the construction and arrangement of the tubes connecting with the valve to permit of this difference of one port as hereinafter described.

In the drawings: Figure l is an elevation of the horn looking from one side thereof; Fig. :2 is a similar View viewed from the reverse side; Figf3 is an elevation of one of the valve pistons detached; Fig. 4 is a perspective view of the valve casing with the tubes connecting therewith; Fig. 5 is a perspective view of the piston removed from the casing; and Figs. 6, 7 and 8 are cross sections showing the operation of the valve in different positions of adjustment.

A is the mouth piece of the horn, B is the flaring end or hell, and C C is the mouthpipe between the mouth piece and bell.

Specification of Letters Patent;

Patented Apr. 4, 1916.

D, D and D are valves, each of whiehin its normal position is adapted to open direct communication between portions of the mam tube, comprised by the member C C and a tube G while in actuated position of the valve direct connection is cut off and a crook is cut in. To accomplish this change with the simple construction of valve having but two ports therein, the valve case F is connected with a branched or forked end of the tube G communicating with one section of the tube C. The branch G is spaced circumferentially of the valve casing from the section C of the tube C and is adapted to be connected therewith through a port H in the piston I when the latter is in normal position. The other branch G is spaced circumferentially of the casing from one end of the crook E and is adapted to be connected therewith by the same port H when the piston I is in its shifted or depressed position. The opposite end of the crook E is connected with the casing F in a circumferentially spaced relation to the branch G and section C as indicated at E and a second port H in the piston I is adapted to connect the sections C and tube E in the depressed or operated position of the piston I.

In other words the construction is such that when the piston is in its normal position, the port H is used to connect the section C and branch G the port H then being out of action; while in the depressed position of the piston, the port H establishes communication between the branch G and one end of the tube E, and the port H couples the section C with the other end E of the tube E. /Vhen either branch G or G is in registration with a port of the piston, the other of said branches will be closed by an imperforate portion of the piston. Thus it will be readily understood that in the normal position there is a direct connection between the section C and the branched tube G, while in the depressed or. operated position there is an indirect con nection from the section C through the crook E and then to the tube G.

Each of the valves is of substantially the same construction and is designed for cutting in a crook, which alters the pitch in the usual manner. As a result of using my improved construction considerable material is saved, the length of the stroke is shortened,

the port areas are made full and unobstructed, and in short the construction is both simplified and cheapened.

What I claim as my invention is 1. In a musical horn, the combination with a valve casing, of two tubes communieating therewith, intermediate its ends, a crook having each of its extremities communicating with said casing, a piston having two' passages extending transversely through the piston, one of which in the normal position of the piston establishes communication between the two said tubes, and in the displaced position of the piston establishes communication between one of said tubes and one end of the crook, while the other passage in the displaced position of the piston establishes communication between the other tube and the other end of the crook and means for subjecting the piston to a non-rotative reciprocation.

2. In a musical horn, the combination with a valve casing, a tube having two branches communicating with said casing, a second tube having communication with the casing, and a crook having each of its extremities in communication with the casing,

of a piston in said casing having passages,

through which in one position of the piston,

one of said branches has communication crook respectively communicate with the other b 'anch and with said second tube.

3. In a musical horn, the combination with a valve casing, of a tube having two branches communicating with said casing through ports spaced longitudinally of the casing, a second tube and a crook each having an extremity in communication with the casing through longitudinally spaced ports, the other extremity of the crook also having communication with the casing, and a piston having two passages, one of which in the normal position of the piston connects the second tube with one of said branches, while in the displaced position of the piston the other passage connects said branch with one extremity of the crook and the firstmentioned passage connects the other branch with the other extremity of the crook.

4. In a musical horn, the combination with a valve casing having three ports circumferentially spaced, and two ports circumferentially spaced and longitudinally spaced from said three ports, of a tube having two branches respectively communicating with one of the three ports and one of the two ports, a second tube communicating with one of the three ports, a crook having its extremities respectively in communication with the other of the three ports and the other of the two ports, and a piston in said casing having passages establishing communication in its normal position between one of said branches and said second tube, and in its displaced position establishing communication between the extremities of the crook and the second tube and the other of said branches respectively.

In testimony whereof I aflix my signature in presence of two witnesses.
